Figure 7: TgNPT1 is essential for parasite virulence in vivo.

Five Balb/c mice were infected with 106 WT (black), Δnpt1 (red) or Δnpt1/tubNPT1 (blue) parasites and monitored for symptoms of toxoplasmosis. The data for WT and Δnpt1 parasite infections are derived from two independent experiments, whereas data for Δnpt1/tubNPT1 infections are derived from a single experiment.
